started its first cogeneration project in 2003, prompted by a program from
NYSERDA (New York State Energy Research and Development Authority) to encourage
installation of such systems by underwriting part, about half, of the capital
cost of installation.
When it went
live, several years later, our Cooperative was the first residential building
in New York State with a cogeneration facility.
It was a cutting edge project that entailed a substantial effort to engineer
for and properly manage heat, noise, and maintenance.
proved successful, providing a substantial portion of the electricity we
consumed, all of the hot water, and a large amount of the steam used to heat
the building in the cold part of the year.
The savings from the cogeneration system amounted to more than a million
dollars during the life of the system.
In 2014 our original cogeneration
units broke down in two separate incidents.
Our engineering advisors recommended that we replace them rather than
repair them, so we embarked on a project to evaluate bidders and ultimately selected
Tecogen as our provider.
Funding for the replacement comes
from NYSERDA, from an insurance reimbursement for the failed units, and from
the Cooperative’s capital fund. The new
cogeneration units will go into service in the very near future.
There are a number of substantial
advances in this installation compared to the original.
The new cogeneration equipment will
be connected on-line to a Tecogen facility that will monitor it continuously,
24 hours a day, seven days a week. This
generation of equipment is off-the-shelf and standardized, making both
operation and maintenance far easier and far less expensive than our first
system. This will result in fewer
demands on our staff.
Backup generator capability
This system, unlike previous
generations, is capable of continuing to produce electricity during a blackout. The capacity of the system is not adequate to
power the entire building in the event of a blackout, but it can power
safety-critical facilities in the building so long as natural gas continues to
flow. We will use it to power these
